Technical/substantive issue
The section currently provides no guidance to actually choosing a baseline
that can in fact be used accessibly.
I propose that the availability of a user agent which meets level-A
conformance to User Agent Accessibility Guidelines 1.0 for the relevant
technology and language be a minimum criterion for the selection of a
baseline.
In this way, selection of a baseline that is not actually accessible
automatically makes it impossible to claim conformance to the
accessibility guidelines. This avoids the situation where it is possible
to construct content that can meet the requirements, but that is not
actually accessible due to the absence of any means for using the baseline
set. Otherwise there is a risk that the value of conformance will be
significantly reduced, since it makes no reliable statement about whether
the content is in fact accessible to real people.
This seems a reasonable requirement given that UAAG is a W3C
recommendation, and does not seem onerous for common web technologies.
